ADMINISTRATIVE REPORT LXVII 
ready for publication. One of these relates to the stone art of 
the aborigines as exemplified and elucidated by the relics 
found in and near the tidewater region adjacent to Chesa- 
peake bay; the second to the fictile art as represented by col- 
lections from eastern United States, especially from the 
mounds. While both reports were substantially complete as 
to letterpress, they were incomplete as to illustrations, and the 
preparation of requisite illustrations was carried forward under 
the supervision of the Ethnologist in Charge and Mr DeLancey 
W. Gill. During July a number of photographs were made, 
for incorporation in the memoir on stone art, by Mr Cushing 
and Mr William Dinwiddie. When the illustrations were com- 
pleted, the memoir was incorporated in the Fifteenth Annual 
Report of the Bureau, which was sent to press during the year. 
During portions of July and August Mr Dinwiddie was 
engaged in the elaboration of notes on a remarkable steatite 
quarry near Clifton, Virginia, and in the transfer of the collec- 
tions to the National Museum. The Clifton quarry is one of 
the largest of the aboriginal excavations of soapstone thus far 
found in eastern United States, and is noteworthy for the 
depth of the cutting and the large amount of fragmentary and 
other material representing the processes of primitive quarry- 
men. Mr Dinwiddie’s work on this material was interrupted 
when he joined the expedition into the Papago country, and 
his report has not been completed. 
Mr Cosmos Mindeleff, who returned from the field about the 
end of September, was occupied during the greater part of 
October in closing his accounts and in other duties connected 
with the termination of long-continued field operations. After- 
ward he began the preparation of a report on his surveys and 
researches. During November, December, and January the 
material was reduced to the form of a memoir on the cliff ruins 
of Canyon de Chelly. In February a preliminary draft of the 
text was brought to substantial completion, and the later por- 
tion of March was spent chiefly in the preparation of illustra- 
tions. During March and April the text was revised and 
rewritten, and toward the end of the latter month it was sub- 
mitted for publication. The preparation of the final drawings
